Cleaning method of chicken feathers to obtain odorless fibers

ABSTRACT

In many cases, the processing of chicken feathers requires washing and disinfection. The unpleasant odor that remains on washed feathers after cleaning is a problem when using feathers or fibers derived from them. The odor of feathers is especially pronounced in high-temperature conditions. The aim of this study is to develop a method for cleaning chicken feathers, which makes it possible to obtain chicken feather fibers without unpleasant odor at a low cost. For this, the chicken feathers were washed according to different programs. Washed and unwashed feather were analyzed using GC-MS method to identify substances that can cause offensive odors at normal temperatures and under higher temperature conditions. The results of different cleaning methods were compared. It was found that the most effective cleaning method in terms of removing volatiles that can cause bad odor from feathers was a main wash with a nonionic detergent after a short prewash with sodium hypochlorite and a finishing treatment with sodium hydroxide solution. It was observed that the surface, internal structure, and mechanical properties of the feathers did not deteriorate as a result of this washing method.

摘要

在许多情况下; 鸡毛的加工需要清洗和消毒. 当使用羽毛或从中提取的纤维时; 清洗后残留在羽毛上的难闻气味是一个问题. 羽毛的气味在高温条件下尤其明显. 本研究的目的是开发一种清洁鸡毛的方法; 以低成本获得无异味的鸡毛纤维. 为此; 根据不同的程序清洗鸡毛. 使用GC-MS方法对清洗过和未清洗过的羽毛进行分析; 以确定在常温和高温条件下会产生难闻气味的物质. 比较了不同清洗方法的清洗效果. 研究发现; 在去除可能导致羽毛异味的挥发物方面; 最有效的清洗方法是在用次氯酸钠进行短暂预洗和氢氧化钠溶液进行整理处理后; 用非离子洗涤剂进行主清洗. 据观察; 这种清洗方法不会导致羽毛的表面、内部结构和机械性能恶化.
